Yes, it is beneficial for the creators of the project to have a lot of participants in their bounty campaign, but for those who participate in the bounty, a large number of participants is not profitable at all, because the common pool is divided into all and the more participants, the less the reward for the work. Recently, a friend of mine showed that he was credited with tokens for $5 for 6 weeks of work in the facebook bounty campaign and all because there were a lot of participants.
